WebJan 7, 2024 · Margin Ranking Loss (nn.MarginRankingLoss) Margin Ranking Loss computes the criterion to predict the distances between inputs. This loss function is very different from others, like MSE or Cross-Entropy loss function. This function can calculate the loss provided there are inputs X1, X2, as well as a label tensor, y containing 1 or -1.
